i Specification of Letters Patent.A v Ptnt-.ed Sept. 20, 1921.

Divided and` this application led August v 5, 192i). Serial No.; 401,409.

To all whom t may 'concern Be it known that I, HERMAN A. PAQUnTru, a citizen of the United States, residing at Chicago, in the county of Oooh and State of Illinois, have invented a new and useful Improvement in a Burner, of which the following is a specification.

My invention relates to burners and more particularly to gas-burners forkstoves, boil- Y ers, and other structures wherein it is desired to maintain lan intense heat or hot flame for domestic and similar purposes. The present application is a division of the applcation for Letters Patent of the United States filed by me June 10th, 1920, Serial Number 887,821, for improvement in a stove and burner.

One of the objects of my invention is the provision of a gas-burner constructed with adjustable means for mixing gas with air so that a uniform and perfect combustion may be obtained. Another object is the pro? vision of a burner of this type that is so constructed that the quantity of fuel consumed is materially less than other burners used for similar purposes. Other objects are the provision of a burner thatis dedependable and effective in performing the functionsfor which it is designed; that is Simple in construction; made of a minimum of parts; easy to install, and comparatively inexpensive to manufacture so that it may be sold fora moderate price.

Other objects will be apparent after my invention is understood and Iprefer to accomplish the divers objects in substantially the manner hereinafter described, reference being now made to the accompanying drawings that` form a partl of this specification.

In the drawings: f

Figure 1 is a vertical axial section of my burner and,

Fig. 2 is a perspective view of the gas and air mixing device employed in connection with the burner.

The drawings are in a sense merely diagrammatical illustrating a typical bnrner, and I have employed the same reference characters to.V designate the same parts throughout the views. v

Referring more particularly to Fig. 1 it will be seen the burner which Il have devised preferably comprises a pipe 17 leading from a suitable source of gas suppilg,

which pipe is threaded upon its end.

Gas

elbow coupling 18 is screwed upon this threaded end of pipe 17 and has its opposite stub disposed vertically to discharge in an upwardly direction and is threaded both interiorly and exteriorly. A tip 19 is tapped into the upturned end of the elbow coupling and is provided with a central bore 2O of suitable diameter that extends into the stub 21 of said tip that is preferably reduced in diameter and extends axially up from the upper surface of the tip 19.

Adjacent its lupper end the bore of the stub 21-is reduced in diameter to provide a discharge orifice 22, as seen in the drawings. A tube 23 is Screwed down upon the exterior threads of the elbow 18, and is provided with lateral ports 24 for the passage of air therethrough into the interior thereof'. This tube 23extends upwardly into the stove or heater a suitable distance and provides a burner on the principle of the well-known Bunsen-type of burner.

From the foregoing it will be seen that the air-and gas are respectively admitted to the burner through ports 24 of the tube and orifice 22 of the tip. In order vto effectively mix the vgas and air, I have provided tube 28 with a regulator, which is shown in detail in Fig. 2 of the drawings. This regulator comprises a split cylindrical tube 32 one end whereof is vprovided with rectangular extensions 33 that are bent laterally inwardly toward the center of the cylinder and are of such length that their corners approximate so as to provide quadrant spaces 84 and a central rectangular space The extensions, when thus formed, provide a. cross at the inner end of the cylinder 32 which is innermost in the tube 23, and the spilt portions of the cylinder 32 permit its adjustment up and down within the tube 23 to regulate the character of flame to be discharged from the end of the burner. It will be found after a little` experiment that but a slight longitudinal movement or adjustment of this regulator within the tube 23 will materially alter or modify the character of the resultant flame.

in its lowervportion,

longitudinally adjustable of said first-mentioned tube and having lateral elements eX- tendng radially thereof to partially inter-V rupt the bore.

2. A gas burner comprising a gas discharge nipple, a, tube surrounding and spaced from the orifice of said nipple and having air inlet ports in its lower portion,

and a flame control device consisting of a blank of metal formed info 'a Cylinder with ifo tongues extending longitudinallytherefrom, said cylinder'belng mounted Within said tube and Said tongues being'bent laterally to HERMAN A. PliQUE'r'TEL ,y y
